Regret is bad for your health!

"When the grief becomes a habit" sang De Andrè in The Hole (musical version of Antoine Paul homology poetry), but there are some who lives his life looking forward, and then only without regret, without taking into consideration! Regret is an unpleasant feeling, I think that nobody can be immune, unless it is totally insensitive or with a personality and consciousness of iron, however, regret is bad for our health.
